Answer:
A. The dominant factor, or allele, is for round seeds.
Explanation:
Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).
He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
During translation to RNA, the nitrogen bases on the DNA molecule are translated to complementary RNA bases. Afterwards, these bases are again used to form amino acids.
Three bases make up a codon, which codes for a specific amino acid. If a base is changed, the codon will become changed. This will result in a different amino acid being produced in and the primary structure of the polypeptide will be altered.
Answer:
D. a protein is formed.
Explanation:
The formation of a dipeptide is the join of two amino acids by a peptide bond, when this occurs a molecule of water is produced, two amino acids are joined together and a double bond forms between the carbon and the nitrogen from the two amino acids . A protein is composed by one or more large chains of amino acids, in other words, a great number of peptide bonds are needed to form a protein not just one which will give a dipeptide or two which will give a tripeptide.
Answer:
Rats and Humans both live on land during all life stages.
Explanation:
I think this because rats don't live in water or anything like that during their lifetimes. Humans also don't live in water during their lifetimes. So that is how I know that they share living on land during all life stages characteristic.
